Definitions
- the present invention relates to a ball retaining cage for ball bearings.
- the invention also relates to a deep groove ball bearing, known by the acronym DGBB in this field.
- bearing units which include a ball retaining cage composed of two symmetrical half-cages coupled together, wherein each half-cage has means for mutual connection with the opposite half-cage, and provides a plurality of partially hemispherical cavities which axially face the hemispherical cavities of the opposite half-cage so as to form, together with the latter cavities, the ball retaining pockets.
- a general object of the invention is to provide a cage and a bearing, of the type mentioned above, which makes the assembly procedure simpler and more economical. Another object of the invention is to improve the sealing and the distribution of lubricating grease inside the bearing unit.
- a cage as defined in Claim 1 According to another aspect of the invention, a bearing unit as defined in Claim 14 is provided. Preferred embodiments of the invention are defined in the dependent claims, the content of which is to be considered as an integral part of the present description.
- Figure 1 is a partial view in axial section of a bearing unit including a cage according to an embodiment of the invention
- Figure 2 is a partial view in axial section of the outer ring of the bearing unit of Figure 1;
- FIGS. 2A and 2B are enlarged views of two details indicated by 2A and 2B in Figure 2;
- Figure 3 is a partial view in axial section of the inner ring of the bearing unit of Figure 1 ;
- Figure 3 A is an enlarged view of the detail indicated by 3 A in Figure 3;
- Figure 4 is a perspective view of the bearing unit of Figure 1, from which the outer ring has been removed for purposes of illustration;
- Figure 5 is a perspective view of the assembly shown in Figure 4, from which part of the cage has been removed;
- Figure 6 is a perspective view in section, taken along a radial plane, of the bearing unit of Figure 1.
- a ball bearing unit designated as a whole at 10, comprises a fixed outer ring 20, an inner ring 30 which is rotatable about an axis of rotation x, a set of balls 40 interposed between the outer and inner rings, and a ball retaining cage 50.
- the bearing unit 10 is a deep groove ball bearing unit (DGBB).
- the cage 50 is composed of two half-cages 51, 52 connected to each other, the cages being advantageously identical to each other and being positioned in a substantially symmetrical way with respect to a radial mid-plane P passing through the bearing, on which plane the centres C of the balls 40 lie.
- the half-cages are preferably made of plastic material, such as PA 66 (polyamide 66) or polyhexamethylene diamide, which are already used for manufacturing retaining cages because of their properties of wear-resistance even with heavy use, low coefficient of friction, formability and resistance to ageing.
- a metal such as steel may be used.
- Each half-cage comprises a basic annular body 53 having one side defined herein as the axially outer side, with reference to the position assumed by the cage in use in the bearing unit in the fully assembled condition.
- Each half-cage is delimited, on its axially outer side, by a flat radial surface 54 which, in use, is preferably placed flush with the respective lateral face 21, 31 of the outer and inner rings.
- An annular groove 55 is formed in a practically central position in the axially outer side of the half-cages, in order to increase the flexibility of the half-cage further and to facilitate its mounting on the bearing, as explained below.
- any terms and expressions indicating positions and directions, such as “radial” and “axial”, are to be understood as referring to the axis of rotation x of the bearing unit.
- the outer ring 20 On its radially inner surface, the outer ring 20 has a central ball race 22 and, on each side of the latter, a corresponding intermediate annular groove 23 having a conical surface 24 (Figure 2B) diverging in an axially outward direction, and a lateral annular groove 25, preferably of trapezoidal shape (Figure 2A), located closer to the axially outer side of the bearing.
- the lateral annular grooves 25 are each radially aligned with a respective lateral annular groove 35 formed in the radially outer surface of the inner ring, on each side of the inner ball race 32 ( Figures 3 and 3A).
- Each half-cage has two radial ridges which are substantially concentric and circumferentially continuous, of which the first ridge projects in a radially outward direction 56 and engaging the lateral groove 25 formed in the outer ring while providing a labyrinth sealing action, and the second ridge 57 projects in a radially inward direction and sealingly engaging the lateral groove 35 formed in the inner ring.
- Each of the ridges 56 and 57 extends from a respective edge 58, 59, which projects in an axially inward direction from the radially outer periphery and from the radially inner periphery, respectively, of the annular body 53.
- This configuration imparts greater flexibility to the edges 58, 59, enabling the two half-cages to be snap-fitted into the respective mounting grooves 25, 35.
- the half-cages From the axially inner side, the half-cages have annular receptacles 60, 61 which open towards the balls.
- the function of the receptacles 60, 61 is to serve as reservoirs for the temporary accumulation of lubricant grease.
- the receptacles open towards the balls with respective conical surfaces 62, 63 diverging towards the ball race, to promote the redistribution of the lubricant grease towards the ball race and towards the intermediate grooves 23.
- each half-cage On its axially inner side, in other words on the side which faces the balls in use, the basic annular body 53 of each half-cage provides a plurality of partially hemispherical cavities 64, each formed by a pair of axial projections 65 having respective concave surfaces 66 lying on the same ideal spherical surface and substantially facing each other in pairs.
- the hemispherical seats of the two half-cages face each other in the axial direction in the assembled condition, and in combination define a plurality of partially spherical pockets for retaining the balls 40 at equal circumferential intervals between the races 22, 32 of the bearing rings.
- Each pocket is part of a respective spherical surface having its centre C lying on the radial mid-plane P.
- a plurality of axial connecting projections 67 extends from the axially inner side of the basic annular body 53 of each half-cage, these projections being placed alternately with the pairs of axial projections 65.
- the connecting projections 67 each have a partially hemispherical concave seat adapted to form a pocket for retaining a corresponding ball in the assembled condition.
- the mutual connecting means are formed by pins 69 projecting axially and corresponding recesses 70 in which the pins 69 can advantageously be snap-locked.
- the pins 69 are bifurcated elastically. As shown in Figure 4, in the assembled condition the axial end surfaces of the projections 65 and 67 are in contact with each other and lie in the radial mid-plane P of the bearing.
- Each half-cage has a portion 72 between two projections 65 and 67 which are consecutive in the circumferential direction, the portion 72 extending axially from the axially inner side of the basic annular body of the half-cage for a distance which is smaller than the axial extension of the projections 65 and 67.
- the portions 72 which in the preferred embodiment are of truncated pyramidal shape, are axially shorter than the other projections 65 and 67 and therefore combine with the latter and with the similar formations on the opposite half-cage to form a plurality of radial passages 73. These passages bring the annular space located between the cage and the inner ball race into direct fluid communication with the annular space located between the cage and the outer ball race.
- the portions 72 have obliquely inclined surfaces 74 arranged in flared pairs so as to diverge in axially outward directions.
- the inclined surfaces 74 are slightly concave.
- the bearing unit is advantageously constructed without any other special sealing means.
